-The gdp per capita distribution has a wide range of values. The maximum gdp per capita is more than 10x the minimum.

-The life expectancy variable is relatively concentrated — over half of the countries have a life expectancy between 70-80 years.

-The unemployment rate of countries is also concentrated with the mean being 7.27% and the 75% quantile being 9.46%. However, the maximum unemployment rate is 37.85%.

GDP vs. Life Expectancy

Figure 1: This figure is a scatter plot of GDP per Capita vs. Life Expectancy for countries in the dataset

As GDP increases, life expectancy increases. A higher GDP means more economic flourishing, allowing more of the country to have access to a healthier lifestyle.
